    lib: Include the size in the error message for mlock
    
    Knowing how much we tried to allocate would be useful if one should need

Two occurrences two weeks ago, then silence. Let's keep an eye on it and see if the next incident gives more information.

Also seen on CML.

This hasn't occurred for 2 months / 120 runs. Before that it was happening on a daily basis and almost on every run. Based on our criteria it can be closed again.
